Pontiac 2005 Montana SV6 Owner's Manual page 339

Notice: If you leave your radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered
by your warranty. Always turn off your radio and
other accessories when jump starting your vehicle.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or the accessory power outlet. Turn off
the radio and all lamps that are not needed. This
will avoid sparks and help save both batteries. And
it could save the radio!
4. Open the hoods and locate the batteries. Find the
positive (+) and negative (−) terminal locations on
each vehicle.
You will not need to access your battery for jump
starting. Your vehicle has a remote positive (+) jump
starting terminal for that purpose.
Squeeze the tabs and swing the cap out of the way
to access the remote positive (+) terminal. You
should always use the remote positive (+) terminal
instead of the positive (+) terminal on your
battery.
CAUTION:
{
An electric fan can start up even when the
engine is not running and can injure you. Keep
hands, clothing and tools away from any
underhood electric fan.
The terminal is located
under a tethered cap at
the front of the underhood
fuse block. See Engine
Compartment Overview on
page 5-12 for more
information on location.
